芳香族反應位向選擇與自容分子軌域中排斥鍵之關係

Relation Between Aromatic Reaction Selectivity and the Repulsive Bond of Approximate SCF MO

摘要


將ZDO(zero differential overlap)近似法及對常區間鍵結(long range bonding)如間位和對位等的斟酌,運用於原子軌域線性結合自容性電場的分子軌域(簡稱LCAO SCF MO)方法中,計算π系(Pi-System)各種特性。芳香族苯環系(如苯、萘、蒽等)中,π電子的共振及長區間鍵的排斥作用,對於其分子中長、鍵角,甚至於整個分子的結構形狀及參與化學反應時的取代位向,影響至鉅。

The characteristics of system for some aromatic compounds are predicted by zero differential overlap MO treatment with all long range bonding included. The repulsive effect of long range bonding ha s a significant influence to the structure of an aromatic molecule as well as to its reaction selectivities.
